Power Runs

Performance Analysis

THOR Racing offers simple power runs on the Dynapack chassis dynamometer to give you a detailed picture of how your engine and drive-train are performing. The unit also provides valuable assistance in the full remapping of electronic engine management and also re-jetting of carburetted systems; so even your classic sports car is catered for within our range of services.

What do I get from a Power Run?

The Chassis Dynamometer (similar to a rolling road)measures....

What do you do / How do you perform the Power Run?

1st we select the nearest gear to a 1:1 ratio as possible.
For most manual cars the top gear is an overdrive gear and thus the previous one is normally the 1:1 drive (so 5th for a 6 speed and 3rd for a 4 speed).
For auto's it is normal to hold them in Drive "D". On the Toyota Supra, for example, it's easy as we can use the Manual mode to hold the gears. Most other makes of auto are difficult and power runs are hard to perform as they keep changing gear.

We then take a steady state control run at 2000rpm to synchronise the Dyno RPM to the car RPM. i.e. work out the rear differential gear ratio if it's unknown. Normally somewhere between 3.8 and 4.2 for most cars.

We can make a power run over any RPM range we like. Normally the run starts at 2000rpm and ends at the beginning of the RPM red line or 500rpm before. 7000rpm for example. THOR staff members always ask the owner first if they have a preference.

The power run is a controlled power run and if the equipment has 4000rpm set to be the maximum RPM for the run no matter what anyone does it will NOT go above that.
So if you aren't happy to hit the rev limiter (which we prefer not to) then we can set this 500rpm below.
Most cars have already reached their max power before rev limiter anyway.

We NEVER give you a printout for Flywheel power and ALWAYS give a figure at the wheels. That way you CAN compare a manual car with an auto one.

If people ask we always use the stock answer of 20% for 2WD rear wheel driven cars, 25% for 4WD and 18% for 2WD front wheel drive cars.

THOR Racing are not prepared to argue about flywheel power as different cars have different transmission losses.
